indeed surprisingly different. The 6 ft. bed of fine horizontally 

 bedded Lower Greensand and the 8 ft. bed of passage strata 

 overlying it, seen north of the farm, are absent. In the northern 

 face of this southern pit the Upper Gault rests directly upon the 

 false-bedded Lower Greensand. The peculiar basement-bed of the 

 northern ^\t is present here, but is se|)arated from the underlying 

 current-bedded sands by one foot or so of obscurely bedded rather 

 dingy grey-brown j)ebbly and gritty sand with polished grains. 

 This contains some of the characteristic phosphatic nodules of the 

 tardefurcata bed, seen in place north of the farm. This thin deposit 

 of sand is evidently a product of the denudation of the tardefurcata 

 bed (see Fig. 3), which is situated at a higher level. Its position 

 just above the false-bedded sands, as well as the presence in it of 

 the small white nodules which characterize the basal beds of the 

 Upper Gault here, shows that it belongs to the period of the trans- 

 gression. The clay above the basement-bed is present to the extent 

 of 4 feet in thickness. It contains the small white nodules, but differs 

 from the corresponding clay seen north of the farm by the presence 

 in its lower part of numerous highly polished quartz-pebbles, up to 

 half an inch in diameter. 



At the west side of pit No. 7, the lowest clay of the Upper Gault 

 is overlain by some imperfectly bedded, crumbled, grey clay, which 

 is met with in other sections aboiit to be described. At the 

 southern end of the pit the false-bedded liower Greensand crops out 

 at the surface, and no Gault is present. The grey clay just mentioned, 

 which overlies the lowest 4 feet of Upper Gault Clay, is of a peculiar 

 type and is readily recognizable in the other sections where it has 

 been seen. It is a soft clay without any well-defined bedding-planes, 

 and is made up of innumerable small pellets, which are for the most 

 part somewhat angular in shape. It might be termed a finely 

 brecciated clay. We think it most probable that the material 

 of which it is composed is the redeposited debris resulting from 

 the denudation of some previously formed, well-consolidated clay. 

 It is relatively unfossiliferous, and appears to contain no ammonites. 

 Here and there it contains small pockets of glauconite, with som.e 

 of which a few specimens oiBelemnites minimus JA%t. are associated. 



It is evident that at Miletree Farm the upper beds of the Lower 

 Greensand, with the passage-beds at the top, were subjected to 

 erosion under the action of strong currents. They stood up here 

 on the sea-floor as a bank of consolidated, though soft, horizontal 

 strata, the sloping sides of which were being planed away. While 

 the fine, lighter material of the 6 ft. bed of sand underlying the 

 tardefurcata bed would, under such conditions, be swept away by 

 currents, some of the nodules and heavier sandy materials of the 

 tardefurcata bed found their way down the slope and, as a residue 

 of the local denudation, formed a constituent of the basal deposit 

 of the Upper Gault. An almost identical section, showing the re- 

 arranged sand 1 foot thick (with nodules from the tardefurcata
